Visualize:

This is a simulation of a resistor-capacitor series circuit, involving a resistor, a capacitor, a battery, and a switch. Note that on the voltage graph, the red line shows the voltage across the resistor, and the blue line shows the voltage across the capacitor.

The sliders allow you to adjust the values of the resistance and the capacitance. What is the largest current that can be achieved? What is the smallest current?

You also have buttons to move the switch from one position to the other, either including the battery in the circuit or removing the battery from the circuit. There is another set of buttons to change the view from actual charge flow (red = positive, blue = negative) to conventional current (all charges flowing are positive).
